My 10-week-old puppy is vomiting, gassy, diarrhea, and peeing a lot.

I have a 10 week old puppy. We just got him last week. He has been throwing up his food, gassy, has diarrhea and peeing a lot of clear liquid, almost like water. He's not house trained so him peeing in the house isn't unusual but the amount is worrying. He is a chihuahua mix. We thought it was that he was eating treats that didn't agree with him but he hasn't had anything in more than 24 hours and he's still sick. He's not dehydrated and he seems to be eating and drinking normally.

You need to take Remington into a vet immediately. I would be extremely concerned that he may have parvovirus, which is a life threatening infection of young unvaccinated puppies. It is also serious that he is still sick in the absence of food, and he needs medical treatment right away. He will need a shot to stop his vomiting, and will need IV fluids for hydration in addition to any other treatment the vet deems necessary. Please take him into a vet now.
